When an S3100-EI Ethernet switch works in the interface address pool mode as a DHCP server, the
only gateway address it can assign to a client is the primary IP address of the interface.
Enabling the Interface Address Pool Mode on Interface(s)
If the DHCP server works in the interface address pool mode, it picks IP addresses from the interface
address pools and assigns them to the DHCP clients. If there is no available IP address in the interface
address pools, the DHCP server picks IP addresses from its global address pool that contains the
interface address pool segment and assigns them to the DHCP clients.
Follow these steps to configure interface address pool mode on interface(s):

Required
By default, a DHCP
server assigns the IP
addresses of the global
address pool to DHCP
clients.
You need to configure an IP address for the interface before enabling the interface address pool mode
on it.
